Optional Input Parameters

1:
tol – double scalar

The required accuracy of the solution. If nag_stat_prob_chisq_noncentral (g01gc) is entered with tol greater than or equal to 1.01.0 or less than 10 × machine precision10×machine precision (see nag_machine_precision (x02aj)), then the value of 10 × machine precision10×machine precision is used instead.
